Definitions
- the invention relates to an arrangement having an electromotive furniture drive and a data device.
- the invention also relates to a method for establishing a communication connection of the electromotive furniture drive to the data device, and to a corresponding electromotive furniture drive.
- Such an arrangement is used, for example, for data transmission between a data device, which is a programming device, for example, and an electromotive furniture drive of a piece of furniture.
- a data device which is a programming device, for example, and an electromotive furniture drive of a piece of furniture.
- operations such as reprogramming, program changes, auxiliary programming, parameter settings, parameter changes, etc., of a control program of the electromotive furniture drive can be performed.
- the programming device can also be a computer.
- the data device is typically coupled, instead of a manual control, which is also referred to as an operating apparatus, to the electromotive furniture drive, i.e., to its controller, via a plug connection.
- a cable pullout safeguard of the plug connection of the manual control is detached, the plug of the manual control is removed from the plug connection on the controller, and a plug of the data device is inserted into the plug connection on the controller.
- Other controllers have a separate plug connection only for data devices. These plug connections are unused in normal operation, however, so that they must be protected accordingly against the penetration of moisture and dust.
- Relevant regulations define corresponding covers and seals for this purpose, which must possibly also be fastened in a specific manner. These covers and seals are to be removed to use the data device and are to be closed again according to the regulations after usage.
- IDE 196 03 318 A1 illustrates an example of this with a description of a control system for electromotively actuable adjustment apparatuses for hospital beds.
- a programming device for example, a laptop, can temporarily be connected using a cable to the bed controller and used for maintenance purposes.
- multimedia devices are used as data devices.
- These can have operating elements as touch switches (touch screens), which are connectable to the respective electromotive furniture drive instead of an existing manual control by means of a matching cable.
- Electromotive furniture drives are known in many different embodiments. They are implemented as linear drives having a linearly adjustable output element or as rotation drives having a rotating output element and have proven themselves very well in practice.
- the linear drives have one or a number of electric motors, wherein a speed-reducing gear is connected downstream from each motor and a further gear, for example, in the form of a threaded spindle gear, is connected downstream from the speed-reducing gear, which generates a linear movement of the output element from the rotational movement of the motor.
- the rotation drives have at least one speed-reducing gear connected downstream from the respective electric motor, wherein the last gear element forms the output element.
- the output element of the respective electromotive furniture drive is connected to a fixed and/or to a movable furniture component, so that during operation of the electric motor, the movable furniture components are adjusted relative to one another.
- the furniture can be implemented as a slatted frame, worktable, bed, reclining surface, treatment table, hospital bed or health care bed, and also as a lifting unit for persons such as lifters or patient lifters.
- auxiliary voltage source which provides electrical energy for switching over or at least initiating a switchover from a turned-off idle state into a turned-on operating state to trigger the switch signals.
- the operating apparatus can be implemented via a wired or wireless (radio/infrared) bidirectional transmission path. Bidirectional means that the operating apparatus can not only conduct control signals to the control device, but rather also can receive signals on the part of the control device, for example.
- the object of the invention is to provide an improved arrangement having an electromotive furniture drive and a data device.
- an arrangement comprises an electromotive furniture drive having a control device, a power supply apparatus, and at least one operating apparatus; a piece of furniture, in which the electromotive furniture drive is installed; and a data device, wherein the electromotive furniture drive and the data device have a communication connection.
- the communication connection between the electromotive furniture drive and the data device has a first transmission path, which is provided for transmitting an identification code of the electromotive furniture drive, and a second transmission path, which is provided for transmitting control data and/or operating data of the electromotive furniture drive.
- the term “communication connection” is to be understood as a data exchange, wherein data are transmitted from the data device to the electromotive furniture drive and vice versa.
- data can be, for example, parameter data, operating data, limiting value data, program data (software), etc., and also control data for controlling the electromotive furniture drive.
- Other data or the operating data can relate to the wear of the electromotive furniture drive.
- the data corresponding to wear can also be calculated or determined from the operating data and/or from the data mentioned at the outset, however.
- a method for establishing a communication connection between an electromotive furniture drive of a piece of furniture and a data device of an arrangement is characterized by the following method steps: (S 1 ) providing an identification code of the electromotive furniture drive of the piece of furniture by means of an identification apparatus of the electromotive furniture drive; (S 2 ) transmitting the identification code provided by the identification apparatus via a first transmission path between the identification apparatus and a communication apparatus of the data device; (S 3 ) identifying the electromotive furniture drive by checking the received identification code; and (S 4 ) establishing the communication connection between the electromotive furniture drive and the communication apparatus of the data device and using a second transmission path between the electromotive furniture drive ( 2 ) and the communication apparatus of the data device.
- the communication connection having two transmission paths advantageously allows a data device not only to be usable for maintenance, service, and diagnosis with the electromotive furniture drive, but rather also a data device, for example, a multimedia device, to be usable for operating purposes.
- devices are defined as multimedia devices which have an input unit, for example, in the form of a touch screen or a keyboard, and which also have an output unit, for example, in the form of a monitor or a display screen and which at least have a capability for optical, electromagnetic, or electrical transmission of data sets.
- Multimedia devices can be implemented as portable and electrically independent from the power supply network and are implemented, for example, as a smart phone or as a cellular telephone or as a mobile wireless telephone.
- a data device for operating purposes is therefore provided if the motors or other components of the electromotive furniture drive can be operated thereby, so that, for example, the adjustment drive which adjusts the piece of furniture can be turned on or off.
- the definition may also be explained in reverse, if an operating device for data purposes can control the respective piece of furniture, therefore, can thus turn on or off the respective adjustment drive of the furniture or other electrical components of the furniture or can at least retrieve its status.
- the data device automatically synchronizes with only this electromotive furniture drive corresponding to the identification code.
- the communication connection for a data exchange is only established and released when this identification has been performed and the electromotive furniture drive is unambiguously recognized in this manner.
- the first transmission path is implemented as wireless
- the second transmission path is implemented as at least partially wireless. It is thus possible that no new cable connections are to be installed. Existing terminals of manual controls are not to be changed. Due to the wireless embodiment of the transmission paths, comfortable setup of the arrangement can be performed, because the previously typical cumbersome coupling can be omitted. Thus, neither is an existing cable connection disconnected nor is a separate line removed again.
- At least one of the two transmission paths is implemented as bidirectional, whereby a data exchange can occur in both directions.
- at least one of the transmission paths is implemented as a unidirectional transmission path.
- first transmission path and the second transmission path are arranged between the electromotive furniture drive and a communication apparatus connected to the data device. Those transmission paths can thus be combined with their associated components in one apparatus.
- the electromotive furniture drive is equipped with an identification apparatus for the first transmission path and with a transmission apparatus for the second transmission path, wherein the communication apparatus has an identification unit for the first transmission path and a transmission unit for the second transmission path.
- the transmission paths can thus be unambiguously assigned.
- the identification apparatus is arranged on and/or in the operating apparatus or an and/or in a part of the electromotive furniture drive. A versatile attachment can thus be performed.
- the identification apparatus is assigned to a piece of furniture. This is performed in the simplest manner as mentioned above, since the operating apparatus or the electromotive furniture drive is assigned to the piece of furniture.
- Other embodiments, wherein the identification apparatus is assigned to the piece of furniture are implemented as connectable to the piece of furniture. These can be connected to an item of information about the patient, for example, to his name.
- the electromotive furniture drive is typically a fixed component of the piece of furniture.
- Other identification apparatuses are indirectly assigned to the piece of furniture, in that they are assigned to a patient, for example, in the form of a patient wristband, a patient data carrier, or the patient file.
- the identification unit is applied and/or attached as an identification code by laser engraving, imprinting, an imprinted or embossed sticker, cutting shaping, reshaping (embossing), molding (injection molding in the case of an injection molded housing), color sequence, and/or color spectrum.
- the identification code is implemented as an optically readable or as an optically recognizable identification code.
- the identification code can be recorded and imaged, for example, by an integrated camera (webcam of the data device). If the identification cutting incorporation is arranged on the manual control of the electromotive furniture drive, the manual control can be held in front of the camera, for example.
- the identification code contains, for example, the progressive serial number of the controller of the electromotive drive (or at least the serial number of a component of the drive set, or a unique identifier of the controller).
- Other identification codes can be implemented as a barcode, as a matrix code, or as a grid code, for example, as a barcode, target code, or as a two-dimensional code/data matrix.
- identification codes are used which are externally visible. This comprises identification codes which are connected or form a connection to the operating apparatus, to the electromotive furniture drive, to an electrical connecting line, to the piece of furniture, or to a patient. Such connections can be mechanical connections or are, with the exception of the patient, integrally joined connections. Visible means that the identification code can be perceived using the human eye. Other embodiments of a visible identification code are invisible to the human eye and can only be perceived by an artificial eye, for example, by a camera or by a scanner.
- identification codes are imaged in electronic form and embodied using electrical identification apparatuses, which comprise electromagnetic, electromechanical, magnetic, or capacitive identification apparatuses. These are described hereafter as electrical identification apparatuses. Electrical identification apparatuses are embodied, for example, as RFID apparatuses or as magnetic strips. In one embodiment, they are arranged inside a housing, which forms the housing of the manual control or of the electromotive furniture drive, for example. Other electrical identification apparatuses are connected to the patient or to the piece of furniture, as described above. Such connections can be mechanical connections, as described at the outset.
- An RFID sticker is a multilayered object which has an electrical RFID circuit and can be installed by means of an adhesive film.
- An. RFID circuit can be a component of a circuit board of an electromotive furniture drive or an operating element or an operating apparatus.
- the camera is arranged in a separate part of the communication unit and is guided by an operator to the identification apparatus to read the identification code.
- the identification apparatus has a stored data value of an identification code and is implemented for an output of the identification code as an optical signal by means of a transmission element.
- a display light of the manual control can thus also be used, for example.
- the display light or a predetermined display light is operated by an upstream microcontroller as a type of flashing light, which is perceived as a continuously lighted display light by the human eye, however.
- the turning on and off of the display light carries the analyzable information for the identification.
- An LED comes into consideration as the display light, which optically displays the status of a storage battery or the operation of an adjustment drive to the user, for example.
- the first transmission path is arranged between the identification apparatus and the identification unit, wherein the second transmission path is arranged between the transmission apparatus and the transmission unit.
- the transmission paths therefore run practically in parallel to one another at different locations. However, they are operated successively, since firstly the first transmission path is operated for the identification and then the second transmission path is operated for the data exchange.
- the first transmission path is an optical transmission path
- the second transmission path is a radio path.
- “Optical” transmission path is also to be understood to mean that the identification code is readable both by an optical device, i.e., by machine, and also by the human eye.
- the first transmission path and the second transmission path are arranged between the identification apparatus and the identification unit.
- the identification unit is used by the transmission unit.
- the first transmission path and the second transmission path form a shared optical transmission path.
- the transmission paths are operated successively. Components may thus be saved.
- the communication apparatus is implemented as a separate auxiliary part.
- This can be, for example, a USB stick, whereby a simple connection to the data device is possible.
- the auxiliary part can be prepared independently from the data device.
- the communication apparatus is at least partially integrated in the data device. Existing functions of the data device can thus also be used.
- the electromotive drive has an acquisition apparatus for acquiring operating data of the electromotive drive.
- the data device is a multimedia device having a touch screen.
- the data device can thus also be used as an operating device.
- the provision of the identification code is performed automatically or in a menu-controlled manner by the data device.
- the operator can start a corresponding program on the data device.
- the transmission in method step (S 2 ) occurs optically, multiple possibilities are provided for the transmission, wherein in one embodiment, imaging of the identification code is performed by means of an optical device. It is also possible that reading of the identification code is performed by a user and input is performed by means of a keyboard, for example, if no reading device is present or an existing one does not function (e.g., weak battery).
- transmission of the identification code is performed by means of light signals. This can be performed particularly rapidly, wherein an incorrect transmission of the identification code can be extremely improbable.
- the light signals can be in the visible range or in the infrared range.
- the light signals are ideally visible to the human eye and are generated by an electrical light source, which is implemented as an LED in one embodiment.
- the electrical light source is switched/controlled by a control unit of the electromotive furniture drive or the operating apparatus.
- the electromotive furniture drive, the piece of furniture, or the operating apparatus ideally comprises the electrical light source.
- the light is turned on and off in an encrypted type of a serial data transmission, which forms the identification code.
- the operating apparatus or the electromotive furniture drive can have a separate light source. In a preferred embodiment of the light source, it is formed by an existing monitoring light of the operating apparatus or the electromotive furniture drive.
- the light source can be turned on and off sufficiently rapidly that it is not perceptible by the human eye. Typical turning-off times of the light are in the range from 5 to 50 ms.
- An electromotive furniture drive of the above-described arrangement is equipped with an identification apparatus for a first transmission path of the communication connection and with a transmission apparatus for a second transmission path of the communication connection.
- the data exchange in the communication connection can be performed extraordinarily simply, since the transmission via the second transmission path occurs in one embodiment via radio.
- Corresponding modules which are available cost-effectively at high quality on the market, can be used as the radio transmitter.
- radio standards such as Bluetooth or WLAN are applied.
- a communication connection to a mobile data device for example, mobile telephone, smart phone, laptop, palmtop, or iPad can thus be performed.

Abstract
Description
- The invention relates to an arrangement having an electromotive furniture drive and a data device. The invention also relates to a method for establishing a communication connection of the electromotive furniture drive to the data device, and to a corresponding electromotive furniture drive.
- Such an arrangement is used, for example, for data transmission between a data device, which is a programming device, for example, and an electromotive furniture drive of a piece of furniture. In this manner, operations such as reprogramming, program changes, auxiliary programming, parameter settings, parameter changes, etc., of a control program of the electromotive furniture drive can be performed. The programming device can also be a computer.
- The data device is typically coupled, instead of a manual control, which is also referred to as an operating apparatus, to the electromotive furniture drive, i.e., to its controller, via a plug connection. For this purpose, a cable pullout safeguard of the plug connection of the manual control is detached, the plug of the manual control is removed from the plug connection on the controller, and a plug of the data device is inserted into the plug connection on the controller. Other controllers have a separate plug connection only for data devices. These plug connections are unused in normal operation, however, so that they must be protected accordingly against the penetration of moisture and dust. Relevant regulations define corresponding covers and seals for this purpose, which must possibly also be fastened in a specific manner. These covers and seals are to be removed to use the data device and are to be closed again according to the regulations after usage.
- IDE 196 03 318 A1 illustrates an example of this with a description of a control system for electromotively actuable adjustment apparatuses for hospital beds. In this case, a programming device, for example, a laptop, can temporarily be connected using a cable to the bed controller and used for maintenance purposes.
- In the case of such arrangements, in which multiple pieces of furniture are set up in direct proximity to one another, for example, in hospitals, nursing homes, showrooms, it can be possible that so-called multimedia devices are used as data devices. These can have operating elements as touch switches (touch screens), which are connectable to the respective electromotive furniture drive instead of an existing manual control by means of a matching cable.
- Electromotive furniture drives are known in many different embodiments. They are implemented as linear drives having a linearly adjustable output element or as rotation drives having a rotating output element and have proven themselves very well in practice. The linear drives have one or a number of electric motors, wherein a speed-reducing gear is connected downstream from each motor and a further gear, for example, in the form of a threaded spindle gear, is connected downstream from the speed-reducing gear, which generates a linear movement of the output element from the rotational movement of the motor. The rotation drives have at least one speed-reducing gear connected downstream from the respective electric motor, wherein the last gear element forms the output element. The output element of the respective electromotive furniture drive is connected to a fixed and/or to a movable furniture component, so that during operation of the electric motor, the movable furniture components are adjusted relative to one another. The furniture can be implemented as a slatted frame, worktable, bed, reclining surface, treatment table, hospital bed or health care bed, and also as a lifting unit for persons such as lifters or patient lifters.
- It is routine to provide such electromotive furniture drives with a so-called network circuit breaker, which more or less disconnects it from the electrical supply network in the event of nonuse. For operation of such a network circuit breaker, a so-called auxiliary voltage source is necessary, which provides electrical energy for switching over or at least initiating a switchover from a turned-off idle state into a turned-on operating state to trigger the switch signals.
- Further consumers which are connectable to a control device of the electromotive furniture drive are, inter alia, massage drives, heaters, lights, etc. The operating apparatus can be implemented via a wired or wireless (radio/infrared) bidirectional transmission path. Bidirectional means that the operating apparatus can not only conduct control signals to the control device, but rather also can receive signals on the part of the control device, for example.
- Operating apparatuses having a full graphic display (display apparatus) and having burned-in (hardware-technology) images are known. The full graphic display displays various images and functions to the consumer.
- The object of the invention is to provide an improved arrangement having an electromotive furniture drive and a data device.
- The object is achieved by the subjects of the independent claims.
- Accordingly, an arrangement comprises an electromotive furniture drive having a control device, a power supply apparatus, and at least one operating apparatus; a piece of furniture, in which the electromotive furniture drive is installed; and a data device, wherein the electromotive furniture drive and the data device have a communication connection. In this case, the communication connection between the electromotive furniture drive and the data device has a first transmission path, which is provided for transmitting an identification code of the electromotive furniture drive, and a second transmission path, which is provided for transmitting control data and/or operating data of the electromotive furniture drive.
- The term “communication connection” is to be understood as a data exchange, wherein data are transmitted from the data device to the electromotive furniture drive and vice versa. These data can be, for example, parameter data, operating data, limiting value data, program data (software), etc., and also control data for controlling the electromotive furniture drive. Other data or the operating data can relate to the wear of the electromotive furniture drive. The data corresponding to wear can also be calculated or determined from the operating data and/or from the data mentioned at the outset, however.
- A method according to the invention for establishing a communication connection between an electromotive furniture drive of a piece of furniture and a data device of an arrangement is characterized by the following method steps: (S1) providing an identification code of the electromotive furniture drive of the piece of furniture by means of an identification apparatus of the electromotive furniture drive; (S2) transmitting the identification code provided by the identification apparatus via a first transmission path between the identification apparatus and a communication apparatus of the data device; (S3) identifying the electromotive furniture drive by checking the received identification code; and (S4) establishing the communication connection between the electromotive furniture drive and the communication apparatus of the data device and using a second transmission path between the electromotive furniture drive (2) and the communication apparatus of the data device.
- The communication connection having two transmission paths advantageously allows a data device not only to be usable for maintenance, service, and diagnosis with the electromotive furniture drive, but rather also a data device, for example, a multimedia device, to be usable for operating purposes.
- In addition, devices are defined as multimedia devices which have an input unit, for example, in the form of a touch screen or a keyboard, and which also have an output unit, for example, in the form of a monitor or a display screen and which at least have a capability for optical, electromagnetic, or electrical transmission of data sets. Multimedia devices can be implemented as portable and electrically independent from the power supply network and are implemented, for example, as a smart phone or as a cellular telephone or as a mobile wireless telephone.
- A data device for operating purposes is therefore provided if the motors or other components of the electromotive furniture drive can be operated thereby, so that, for example, the adjustment drive which adjusts the piece of furniture can be turned on or off. The definition may also be explained in reverse, if an operating device for data purposes can control the respective piece of furniture, therefore, can thus turn on or off the respective adjustment drive of the furniture or other electrical components of the furniture or can at least retrieve its status.
- By means of the first transmission path it is possible to perform an identification of the electromotive furniture drive for an unambiguous assignment. After the recognition of the identification code, the data device automatically synchronizes with only this electromotive furniture drive corresponding to the identification code. The communication connection for a data exchange is only established and released when this identification has been performed and the electromotive furniture drive is unambiguously recognized in this manner.
- In one embodiment, it is provided that the first transmission path is implemented as wireless, and the second transmission path is implemented as at least partially wireless. It is thus possible that no new cable connections are to be installed. Existing terminals of manual controls are not to be changed. Due to the wireless embodiment of the transmission paths, comfortable setup of the arrangement can be performed, because the previously typical cumbersome coupling can be omitted. Thus, neither is an existing cable connection disconnected nor is a separate line removed again.
- In the case in which, for example, in a hospital, multiple pieces of furniture are in direct proximity to one another, all data devices and all pieces of furniture or all electromotive furniture drives, respectively, are ready to receive signals in a wireless manner. However, since the communication connection uses two transmission paths, namely one for identification and one for data transmission, an unambiguous assignment occurs between data device and electromotive drive to be assigned.
- Furthermore, it is provided that at least one of the two transmission paths is implemented as bidirectional, whereby a data exchange can occur in both directions. In a simplified and preferred form, however, at least one of the transmission paths is implemented as a unidirectional transmission path.
- In a further embodiment, the first transmission path and the second transmission path are arranged between the electromotive furniture drive and a communication apparatus connected to the data device. Those transmission paths can thus be combined with their associated components in one apparatus.
- It is provided that the electromotive furniture drive is equipped with an identification apparatus for the first transmission path and with a transmission apparatus for the second transmission path, wherein the communication apparatus has an identification unit for the first transmission path and a transmission unit for the second transmission path. The transmission paths can thus be unambiguously assigned.
- In still a further embodiment, it is provided that the identification apparatus is arranged on and/or in the operating apparatus or an and/or in a part of the electromotive furniture drive. A versatile attachment can thus be performed.
- In another embodiment, the identification apparatus is assigned to a piece of furniture. This is performed in the simplest manner as mentioned above, since the operating apparatus or the electromotive furniture drive is assigned to the piece of furniture. Other embodiments, wherein the identification apparatus is assigned to the piece of furniture, are implemented as connectable to the piece of furniture. These can be connected to an item of information about the patient, for example, to his name. The electromotive furniture drive is typically a fixed component of the piece of furniture. Other identification apparatuses are indirectly assigned to the piece of furniture, in that they are assigned to a patient, for example, in the form of a patient wristband, a patient data carrier, or the patient file.
- In one embodiment, the identification unit is applied and/or attached as an identification code by laser engraving, imprinting, an imprinted or embossed sticker, cutting shaping, reshaping (embossing), molding (injection molding in the case of an injection molded housing), color sequence, and/or color spectrum. In this embodiment, the identification code is implemented as an optically readable or as an optically recognizable identification code. The identification code can be recorded and imaged, for example, by an integrated camera (webcam of the data device). If the identification cutting incorporation is arranged on the manual control of the electromotive furniture drive, the manual control can be held in front of the camera, for example. The identification code contains, for example, the progressive serial number of the controller of the electromotive drive (or at least the serial number of a component of the drive set, or a unique identifier of the controller). Other identification codes can be implemented as a barcode, as a matrix code, or as a grid code, for example, as a barcode, target code, or as a two-dimensional code/data matrix.
- In principle, identification codes are used which are externally visible. This comprises identification codes which are connected or form a connection to the operating apparatus, to the electromotive furniture drive, to an electrical connecting line, to the piece of furniture, or to a patient. Such connections can be mechanical connections or are, with the exception of the patient, integrally joined connections. Visible means that the identification code can be perceived using the human eye. Other embodiments of a visible identification code are invisible to the human eye and can only be perceived by an artificial eye, for example, by a camera or by a scanner.
- Other identification codes are imaged in electronic form and embodied using electrical identification apparatuses, which comprise electromagnetic, electromechanical, magnetic, or capacitive identification apparatuses. These are described hereafter as electrical identification apparatuses. Electrical identification apparatuses are embodied, for example, as RFID apparatuses or as magnetic strips. In one embodiment, they are arranged inside a housing, which forms the housing of the manual control or of the electromotive furniture drive, for example. Other electrical identification apparatuses are connected to the patient or to the piece of furniture, as described above. Such connections can be mechanical connections, as described at the outset.
- Therefore, for example, barcode stickers, numbered stickers, RFID stickers, RFID circuits, bed clips, patient cards, patient wristbands come into consideration as practical embodiments of identification apparatuses. An RFID sticker is a multilayered object which has an electrical RFID circuit and can be installed by means of an adhesive film. An. RFID circuit can be a component of a circuit board of an electromotive furniture drive or an operating element or an operating apparatus.
- It is also possible that the camera is arranged in a separate part of the communication unit and is guided by an operator to the identification apparatus to read the identification code.
- In an alternative embodiment, the identification apparatus has a stored data value of an identification code and is implemented for an output of the identification code as an optical signal by means of a transmission element. A display light of the manual control can thus also be used, for example. In this embodiment, the display light or a predetermined display light is operated by an upstream microcontroller as a type of flashing light, which is perceived as a continuously lighted display light by the human eye, however. The turning on and off of the display light carries the analyzable information for the identification. An LED comes into consideration as the display light, which optically displays the status of a storage battery or the operation of an adjustment drive to the user, for example.
- In one embodiment, the first transmission path is arranged between the identification apparatus and the identification unit, wherein the second transmission path is arranged between the transmission apparatus and the transmission unit. The transmission paths therefore run practically in parallel to one another at different locations. However, they are operated successively, since firstly the first transmission path is operated for the identification and then the second transmission path is operated for the data exchange.
- It is provided that the first transmission path is an optical transmission path, and the second transmission path is a radio path. “Optical” transmission path is also to be understood to mean that the identification code is readable both by an optical device, i.e., by machine, and also by the human eye.
- In an alternative embodiment, the first transmission path and the second transmission path are arranged between the identification apparatus and the identification unit. The identification unit is used by the transmission unit.
- In this case, the first transmission path and the second transmission path form a shared optical transmission path. However, the transmission paths are operated successively. Components may thus be saved.
- In still a further embodiment, the communication apparatus is implemented as a separate auxiliary part. This can be, for example, a USB stick, whereby a simple connection to the data device is possible. The auxiliary part can be prepared independently from the data device.
- In an alternative embodiment, the communication apparatus is at least partially integrated in the data device. Existing functions of the data device can thus also be used.
- In still a further embodiment, the electromotive drive has an acquisition apparatus for acquiring operating data of the electromotive drive.
- In a further embodiment, the data device is a multimedia device having a touch screen. The data device can thus also be used as an operating device.
- In another embodiment, the provision of the identification code is performed automatically or in a menu-controlled manner by the data device. The operator can start a corresponding program on the data device.
- If the transmission in method step (S2) occurs optically, multiple possibilities are provided for the transmission, wherein in one embodiment, imaging of the identification code is performed by means of an optical device. It is also possible that reading of the identification code is performed by a user and input is performed by means of a keyboard, for example, if no reading device is present or an existing one does not function (e.g., weak battery).
- In an alternative embodiment, transmission of the identification code is performed by means of light signals. This can be performed particularly rapidly, wherein an incorrect transmission of the identification code can be extremely improbable.
- The light signals can be in the visible range or in the infrared range. The light signals are ideally visible to the human eye and are generated by an electrical light source, which is implemented as an LED in one embodiment. The electrical light source is switched/controlled by a control unit of the electromotive furniture drive or the operating apparatus. The electromotive furniture drive, the piece of furniture, or the operating apparatus ideally comprises the electrical light source. The light is turned on and off in an encrypted type of a serial data transmission, which forms the identification code. For this purpose, in one embodiment, the operating apparatus or the electromotive furniture drive can have a separate light source. In a preferred embodiment of the light source, it is formed by an existing monitoring light of the operating apparatus or the electromotive furniture drive. The light source can be turned on and off sufficiently rapidly that it is not perceptible by the human eye. Typical turning-off times of the light are in the range from 5 to 50 ms.
- An electromotive furniture drive of the above-described arrangement is equipped with an identification apparatus for a first transmission path of the communication connection and with a transmission apparatus for a second transmission path of the communication connection.
- The data exchange in the communication connection can be performed extraordinarily simply, since the transmission via the second transmission path occurs in one embodiment via radio. Corresponding modules which are available cost-effectively at high quality on the market, can be used as the radio transmitter. However, it is also possible that radio standards such as Bluetooth or WLAN are applied. A communication connection to a mobile data device, for example, mobile telephone, smart phone, laptop, palmtop, or iPad can thus be performed.
- Further characteristics and features result from the following description of a preferred exemplary embodiment and are the subject matter of further dependent claims.
- The invention will be explained in greater detail on the basis of the appended drawings. In the figures:
-
FIG. 1 shows a schematic block diagram of an exemplary embodiment of an arrangement according to the invention having a first exemplary embodiment of an electromotive furniture drive according to the invention; -
FIG. 2 shows the schematic block diagram according toFIG. 1 having a second exemplary embodiment of the electromotive furniture drive according to the invention; and -
FIG. 3 shows a schematic flow chart of an exemplary embodiment of a method according to the invention. -
FIG. 1 shows a schematic block diagram of an exemplary embodiment of anarrangement 1 according to the invention having an exemplary embodiment of anelectromotive furniture drive 2 according to the invention. - The arrangement has here the
electromotive furniture drive 2, a piece offurniture 3, which is only schematically indicated by a rectangular box, and adata device 21. - The
electromotive furniture drive 2 is assigned to the piece offurniture 3, which is a hospital bed or health care bed in thearrangement 1 of this exemplary embodiment. For this purpose, theelectromotive furniture drive 2 is embodied in a type of intellectual property protection corresponding to the use, which will not be described in greater detail here, however. - Other types of furniture have already been mentioned at the outset, are not shown in greater detail in the figures, and can therefore be implemented as an armchair, couch, conventional household bed, or as a slatted frame. Types similar to furniture, wherein the
arrangement 1 can certainly be used, however, are formed by rehabilitation devices such as patient lifters or bathtub lifters or the like, but also fall under the definition of furniture, since they are implemented as furnishings, i.e., as fixtures predominantly in interiors. - The
data device 21 can be, for example, a read device, a write device (programming device), mobile telephone, laptop, etc., or a mobile device in general. In this exemplary embodiment, thedata device 21 is a multimedia device in a patient room of a hospital and/or nursing home, wherein this multimedia device is attached above the piece offurniture 3 implemented as a hospital bed and/or health care bed, for example, over its foot part on a wall or hanging down from the ceiling. This multimedia device is also equipped as adata device 21 in this example with a display screen and a touch screen. i.e., the operation of theelectromotive furniture drive 2 of the piece offurniture 3 can be performed by thedata device 21 when a communication connection is established between thedata device 21 and theelectromotive furniture drive 2. - This communication connection has a
first transmission path 24 and asecond transmission path 25. Firstly, an identification of theelectromotive furniture drive 2 is performed via thefirst transmission path 24. After completed identification, a data exchange is carried out with theelectromotive furniture drive 2 via thesecond transmission path 25. This will be described in detail hereafter. - The
data device 21 is connected via aconnection 22 to acommunication apparatus 17. Thecommunication apparatus 17 is used to establish and operate the communication connection between thedata device 21 and theelectromotive furniture drive 2. Thefirst transmission path 24 and thesecond transmission path 25 are arranged between thecommunication apparatus 17 and theelectromotive furniture drive 2, and will be described in greater detail hereafter together with thecommunication apparatus 17. - The
data device 21 is additionally connected here via abidirectional terminal 23 to an intranet and/or the Internet or another data network. Thus, for example, remote maintenance of theelectromotive furniture drive 2 can be performed via the Internet when the communication connection is established. - The term “data exchange” is to be understood not only as readout, transmission, and writing of data values, for example, operating data of the
electromotive furniture drive 2, but rather also a transmission of data values of control data, which contain control commands for theelectromotive furniture drive 2. In this manner, thedata device 21 can be used in the embodiment as a multimedia device having touch screen for operating theelectromotive furniture drive 2 of the piece offurniture 3. Possible operating restrictions for a patient who can be located in the piece offurniture 3 implemented in the example as the hospital/health care bed, due to corresponding apparatuses, which will not be described here, can be possible. - In this exemplary embodiment, the
electromotive furniture drive 2 comprises threeadjustment drives 4 implemented as linear drives, a control device 5, apower supply apparatus 8, and anoperating apparatus 10. - One construction of the adjustment drives 4 is shown on the
right adjustment drive 4 having reference signs as representative of the others. The adjustment drives 4 have, depending on the rotational direction of anelectric motor 4 a (not shown in greater detail), ahousing 4 b, and an extendable andretractable lifting pipe 4 c, on the free end of which an attachment part in the form of afork head 4 d is attached. A further attachment part, for example, also in the form of a further fork head (not shown) is fastened on thehousing 4 b of theadjustment drive 4. The respective attachment part is respectively connected in a way not shown in greater detail to a furniture component of the piece offurniture 3, so that upon operation of theelectric motor 4 a, the furniture components respectively attached to theadjustment drive 4 move relative to one another. The threeadjustment drives 4 are connected to the control device 5 by means ofmotor connection lines 4 e. The respective connection can be embodied, for example, by means of plug connectors in different types of intellectual property protection, for example, spray water protection. - The control device 5 is shown in
FIGS. 1 and 2 as a rectangular block and has multiple apparatuses, not all of which are shown here. Thus, for example, one apparatus thereof is identified as a motor controller, which can be implemented as a relay controller having relay switches and/or as a semiconductor circuit having semiconductor switches. Furthermore, a so-called controller, for example, a microcomputer, can be provided, which has associated control software and one or more memories. - The control device 5 additionally comprises an acquisition apparatus 6 having a
storage apparatus 6 a, and atransmission apparatus 7. - The acquisition apparatus 6 acquires operating data of the
electromotive drive 2 and stores it either completely or selectively, for example, in a time-dependent, load-dependent, calculated, or estimated manner, in thestorage apparatus 6 a. - The term “operating data” is to be understood, for example, in the simplest case as the frequency of exceeding the turning-on duration of a
respective adjustment drive 4. Furthermore, other data can be acquired, which, as further operating data, represent an image of the overall performed operation of theelectromotive drive 2, for example, maximum operating duration, average operating duration, maximum load/power consumption, average power consumption, values for the analysis of wear calculated from the data, etc. In addition, data on the operation of the drive can also come in to consideration for the operating data, for example, control software, individual control programs, control parameters, etc. - The
transmission apparatus 7 is used, when the communication connection is established, for data exchange of the operating data, for example, the stored data in thestorage apparatus 6 a and in other memories of the control device 5, and for data exchange of control data for operating theelectromotive furniture drive 2 via thecommunication apparatus 17 with thedata device 21, which will be explained in detail hereafter. Thus, not only can operation of theelectromotive furniture drive 2 be performed in a simple manner via thedata device 21, but rather also a readout of service data, which are stored in thestorage apparatus 6 a and in other memories of the control device 5, when the communication connection is established. The respective associated data exchange can also be performed bidirectionally, i.e., thetransmission apparatus 7 is implemented both for transmitting and also for receiving data, for example, control data, limiting values, setting values, software, etc., for controlling theelectromotive furniture drive 2, and for writing in thestorage apparatus 6 a and in other memories of the control device 5. The data exchange will be explained in greater detail hereafter. - Furthermore, the control device 5 is coupled to the
operating apparatus 10, which will be described in greater detail hereafter, via acontrol connection 26. Thecontrol connection 26 can be embodied as a wired connection and/or a wireless connection, for example, as a radio link or infrared link. In this exemplary embodiment, thecontrol connection 26 is implemented as bidirectional and wire-bound. A connection of thecontrol connection 26 to the control device 5 is a plug connection here, for example, in a suitable type of intellectual property protection. - The
power supply apparatus 8 is electrically connected to the control device 5 and is implemented, for example, having an isolating transformer, rectifier, and filter circuit or as a switched-mode power supply. Thepower supply apparatus 8 is connected according to the illustration according toFIG. 1 via anetwork cable 9 to anetwork plug 9 a, wherein in another embodiment (not shown in greater detail), thenetwork plug 9 a can be arranged on a network circuit breaker (also not shown). In another embodiment, this network circuit breaker can be integrated in thepower supply apparatus 8. It is also to be noted that thepower supply apparatus 8 is then provided according to the illustration according toFIG. 1 with an enclosing housing, so that thenetwork plug 9 a can be attached or molded on the housing. - In a refining embodiment (not shown in greater detail, however), the
power supply apparatus 8 is inserted into the housing of the control device 5 or ahousing 4 b of the adjustment drives 4 or attached thereon, wherein one or two of the adjustment drives 4 can be constructed like a double drive (not shown in greater detail), wherein at least oneelectric motor 4 a, but preferably twoelectric motors 4 a can be accommodated in a shared housing. - The
operating apparatus 10 comprises in this exemplary embodiment at least oneoperating section 11 havingswitch operating elements display apparatus 14, and anidentification apparatus 15. These components are arranged in or on a housing (not shown in greater detail) of theoperating apparatus 10. - A further embodiment (not shown in greater detail) of the
arrangement 1 provides a network-independent power supply in the form of a storage battery. This can be arranged additionally to thepower supply apparatus 8 and electrically connected thereto, however, it can also replace thepower supply apparatus 8 in a further embodiment. A relatively small construction of apower supply apparatus 8 is then required, however, which is implemented as a charging device of the storage battery. - By means of the
operating apparatus 10, the relay switches or the semiconductor switches of the control device 5 and therefore the adjustment drives 4 can be turned on and off, for example, via control currents, wherein the power switches of the relay switches or the semiconductor switches switch the high motor current of therespective adjustment drive 4. - The respective functions, for example, adjusting an
adjustment drive 4 in one direction and in the opposite direction, can be actuated using theswitch operating elements operating section 11 of theoperating apparatus 10. Furtherswitch operating elements electromotive furniture drive 2 of the piece offurniture 3. Theswitch operating elements display apparatus 14 as touch switches (touch screen switches). - The control device 5 of the
electromotive furniture drive 2 of the piece offurniture 3, which is a hospital/health care bed in this exemplary embodiment, can additionally be connected to a further so-called lockout box, which is only usable by authorized personnel (health care personnel), using which control functions can be blocked and released for the user, which is not described in greater detail here. - The
display apparatus 14 can be, in a simple embodiment, only an optical report display, for example, a light-emitting diode, for a respective turned-on or blocked function, for example. However, it is also possible that thedisplay apparatus 14 is implemented as a full graphic display screen and/or a display screen, for example, having burned-in images. A simple report display can additionally be provided as a light-emitting diode, for example. - The
identification apparatus 15 has an identification code of theelectromotive furniture drive 2 of the piece offurniture 3 and is used for the unambiguous identification of theelectromotive furniture drive 2 of the piece offurniture 3 to establish the communication connection of theelectromotive furniture drive 2 of the piece offurniture 3 to thedata device 21. The communication connection to thedata device 21 is carried out by thecommunication apparatus 17 in conjunction with theidentification apparatus 15 and thetransmission apparatus 7. - In a first, simple variant, the
identification apparatus 15 has a permanent, optical identification code, which is visible and/or machine-readable. The term “visible” is also to be understood to mean that the identification code is also only visible in a specific wavelength range, for example, only in the infrared range, but is readable using a corresponding tool, wherein the identification code is then not visible to the human eye. The identification code can be formed by infrared light signals, wherein a special or a standardized transmission protocol, for example, according to the IrDA standard (Infrared Data Association) is used in a simplified manner. - The identification code contains, for example, the running serial number of the
electromotive furniture drive 2 or its control device 5 for assignment of the respective data of the data exchange to therespective furniture drive 2 or its control device 5. The identification code can also have another character sequence alternatively or additionally to the serial number. - For this purpose, the
identification apparatus 15 of this first variant is attached to theoperating apparatus 10 in a suitable manner. This can be, for example, on the surface of the housing of theoperating apparatus 10, wherein an application is possible by laser engraving, imprinting, an imprinted or embossed sticker, cutting shaping, reshaping (embossing), molding (injection molding in the case of an injection molded housing), color sequence, color spectrum, etc. - The attachment location of this first variant of the
identification apparatus 15 is arranged in this example on the housing of theoperating apparatus 10. However, it can also be arranged on its suspension (hooks) or in general on the housing of a component of the electromotive furniture drive 2 (operatingapparatus 10, control device 5,adjustment drive 4, cable [control connection 26,network connection cable 9,motor connection line 4 c], connecting linkage, etc.). - The identification code of this first variant of the
identification apparatus 15 can also be arranged and/or attached on a component (for example, in the service documents) associated with theelectromotive furniture drive 2 and/or the piece offurniture 3. - A second variant of the
identification apparatus 15 has atransmission element 16. Thetransmission element 16 is implemented in this exemplary embodiment as a lighting means, for example, a light-emitting diode (LED). In an alternative embodiment, thedisplay apparatus 14 in the simple embodiment as an optical report display, for example, as a light-emitting diode, can be used as thetransmission element 16. The identification code is stored in this variant in theidentification apparatus 15 as a stored data value. It is also possible that theidentification apparatus 15 is implemented for the purpose of reading out the identification code as a stored data value from a memory of the control device 5 or thestorage apparatus 6 a. - In another manner, the
display apparatus 14 can be implemented as thetransmission element 16. A full graphic display screen can be provided as thedisplay apparatus 14 in this case, which brings a barcode or a two-dimensional matrix code to optical display, wherein thedisplay apparatus 14 can be implemented as an LCD display without background illumination, but in a preferred embodiment has a lighting apparatus, or adisplay apparatus 14 as a full graphic display screen is embodied as self-lighting. - An essential advantage of the optical transmission path and the
optical identification apparatus 15 and also of theoptical transmission element 16 is still to be mentioned. The direction and the intensity of these transmission paths may be determined and configured very easily. Atransmission element 16 implemented as a yellow light-emitting diode, for example, generally has a small light emission angle and generally has a low luminosity, so that the data it transmission originating therefrom naturally has a short range of approximately 10 cm. For this purpose, a range reducing component, for example, in the form of a resistor or another type of component having voltage limiting properties, can also be connected upstream of the light-emitting diode. The essential advantage is that another similar piece of furniture, which is set up nearby the piece offurniture 3, is excluded from the identification and only the piece offurniture 3 is identified. - The data value of the identification code which is stored or read out by the
identification apparatus 15 is then adapted by theidentification apparatus 15 so as to output it as an optical signal, for example, a sequence of optical brightness pulses, by means of thetransmission element 16. - The identification code provided by the
identification apparatus 15 is transmitted via thefirst transmission path 24 to thecommunication apparatus 17 of thedata device 21. Thecommunication apparatus 17 comprises here acommunication control unit 17 a, anidentification unit 18 having anidentification element 19, and atransmission unit 20. - The
identification element 19 is implemented to read the identification code provided by theidentification apparatus 15. - The type of the identification code can be, for example, a sequence of numbers, a barcode, a 2-D barcode, a grid, or also a light code.
- In the first variant of the
identification apparatus 15, theidentification element 19 is a camera, for example, which records, images, and relays the optically readable identification code in a way not explained in greater detail to theidentification unit 18. If the identification code is a barcode, for example, theidentification element 19 can be a corresponding barcode read apparatus, for example. - In the second variant of the
identification apparatus 15, theidentification element 19 is implemented, for example, as a phototransistor, a suitable transceiver element, or as a phototransistor and transmission diode. Theidentification element 15 receives the optical pulses or signals, which contain the identification code, from thetransmission element 16 and relays them to theidentification unit 18. - The
first transmission path 24 can also be implemented as bidirectional in the second variant, wherein, for example, theidentification element 19 transmits a start signal, receipt signal, query signal, or the like, which is generated by theidentification unit 18, to theidentification apparatus 15. Thefirst transmission path 24 is preferably implemented as wireless and optical here. - Thus, for example, in the second variant having bidirectional
first transmission path 24, the identification code can alternatively be requested so that a report means, for example, a colored LED, displays this request. A user can then input the identification code in greatly varying ways, for example, by button actuation (special button, button combinations, online via email, via mobile wireless by SMS, etc.), or cause the identification code to be provided and transmitted. - The
identification unit 18 checks the identification code received from theidentification element 19 and/or compares it to a value stored in thecommunication apparatus 17. If the identification code has been recognized in this manner, thecommunication control unit 17 a carries out a release of thetransmission unit 20 of thecommunication apparatus 17 for the establishment of the communication connection to thetransmission apparatus 7 of the control device 5 of theelectromotive furniture drive 2 via asecond transmission path 25, which is bidirectional here. Thesecond transmission path 25 is preferably a wireless radio path here, but can alternatively also be implemented as optical, for example, as an infrared path, acoustically, for example, ultrasound transmission, inductively, or capacitively. - The
transmission apparatus 7 of the control device 5 of theelectromotive furniture drive 2 is equipped with a transceiver for the second,bidirectional transmission path 25, to communicate with thetransmission unit 20 of thecommunication apparatus 17. - The
communication control unit 17 a of thecommunication apparatus 17 in turn transmits the data of the data exchange via theconnection 22 to thedata device 21 and back. Theconnection 22 is also implemented as bidirectional here. - In this manner, an unambiguous assignment is performed between the
data device 21 and theelectromotive furniture drive 2 during the establishment of the communication connection. Furthermore, a synchronization of the data exchange via thesecond transmission path 25 is thus also ensured. An interruption of thecontrol connection 26 by removing theoperating apparatus 10 or installing or plugging in an additional wired connection is not necessary. - The
first transmission path 24 and thesecond transmission path 25 are arranged in the first exemplary embodiment locally at different positions and are operated in chronological succession. I.e., thefirst transmission path 24 is arranged between theidentification apparatus 15 of theoperating apparatus 10 and theidentification unit 18 of thecommunication apparatus 17, wherein thesecond transmission path 25 is arranged between thetransmission apparatus 7 of the control device 5 and thetransmission unit 20 of thecommunication apparatus 17. - The
communication apparatus 17 can be implemented as an auxiliary part, for example, as a USB stick or a so-called dongle. To carry out the identification via thefirst transmission path 24, thecommunication apparatus 17 having theidentification element 19 is placed on theoperating apparatus 10 so that theidentification element 19 is arranged on thetransmission element 16 or is congruent therewith or has an optical visual connection thereto. Starting of the identification operation can be performed via thedata device 21. It is also possible that the identification operation to establish the communication connection is only activated by actuating some type ofswitch operating element operating section 11 or an operating element (not shown) provided for this purpose of theoperating apparatus 10. - Alternatively, the
communication apparatus 17 can be completely or partially integrated in thedata device 21, for example, a webcam of thedata device 21 or another camera or a transceiver apparatus having Bluetooth wireless technology can be used as theidentification element 19. - The established communication connection and data exchange operations can be displayed by one or more further display means.
-
FIG. 2 shows the schematic block diagram according toFIG. 1 having a second exemplary embodiment of theelectromotive furniture drive 2 according to the invention. - In contrast to the first exemplary embodiment according to
FIG. 1 , in the second exemplary embodiment, thefirst transmission path 24 and thesecond transmission path 25 are locally arranged at the same position, wherein thesecond transmission path 25 runs via thecontrol connection 26. Thefirst transmission path 24 and thesecond transmission path 25 are also operated in chronological succession in the second exemplary embodiment, however. - Furthermore, it is preferable in the second exemplary embodiment that the
first transmission path 24 and thesecond transmission path 25 between theidentification apparatus 15 of theoperating apparatus 10 and theidentification unit 18 of thecommunication apparatus 17 are implemented as optical, bidirectional transmission paths. - The
identification unit 18 and thetransmission unit 20 of thecommunication apparatus 17 are connected to one another here via atransmission connection 27. Thetransmission connection 27 is a bidirectional transmission path, which is wire-bound here. - The identification operation occurs in the second exemplary embodiment, as in the first exemplary embodiment, via the
first transmission path 24. - As soon as the identification by the
identification unit 18 is completed, the release is performed via thecommunication control unit 17 a to establish the communication connection, wherein thetransmission unit 20 is activated. Thetransmission unit 20 is then connected by thetransmission connection 27 to theidentification unit 18 and transmits, by way of thesecond transmission path 24, which is now set up between theidentification element 19 and thetransmission element 16, and which previously formed thefirst transmission path 24, the respective data via the established communication connection. The communication connection to thetransmission apparatus 7 of the control device 5 of theelectromotive furniture drive 2 is established such that thecontrol connection 26 is also used as the second transmission path. Thesecond transmission path 25 therefore has three components, namely the wire-boundtransmission connection 27, the opticalfirst transmission path 24, and the wire-boundcontrol connection 26. - In one variant, it is possible that the optical report display of the
display apparatus 14 in the simple embodiment, for example, a light-emitting diode, is used as thetransmission element 16. - Furthermore, the
transmission element 16 having theidentification apparatus 15 can, upon every actuation of aswitch operating element operating section 11 of theoperating apparatus 10, provide or transmit both the identification code and also, in chronological succession thereafter, the data values of a data exchange of the operating data. The transmission of the identification code and the data values is performed at such a high frequency that they are not recognizable to a user and only normal lighting of the display means is perceived. - Also in the second exemplary embodiment, re-plugging, replacement, or removal of the
operating apparatus 10 or installing of a new wired connection to thedata device 21 is not necessary to establish a communication of theelectromotive furniture drive 2 to thedata device 21. - Also in this case, the
communication apparatus 17 can alternatively be completely or partially integrated in thedata device 21, for example, a webcam of thedata device 21 or another camera or a transceiver apparatus having Bluetooth wireless technology can be used as theidentification element 19. -
FIG. 3 shows a schematic flow chart of an exemplary embodiment of a method according to the invention for establishing a communication connection between theelectromotive furniture drive 2 of the piece offurniture 3 and thedata device 21. - Firstly, in a first method step S1, an identification code of the
electromotive furniture drive 2 of the piece offurniture 3 is provided. The provision can be performed automatically, however, it can also be requested in a menu-controlled manner by means of thedata device 21, for example, wherein a corresponding display appears on the display screen of thedata device 21, for example. - Then, in a second method step S2, a transmission of the identification code is performed via the
first transmission path 24 between theidentification apparatus 15 and theidentification unit 18. The transmission is performed optically, as already described above. - In a third method step S3, a check of the received identification code is performed by means of comparison to previously stored data values. In the event of positive check result, an assignment of the identification code thus recognized of the
electromotive furniture drive 2 to previously stored data is performed. - Finally, in a fourth method step S4, the communication connection between the
electromotive furniture drive 2 of the piece offurniture 3 and thedata device 21 is established, wherein thesecond transmission path 25 between thetransmission unit 20 and the transmission apparatus 6 of the control device 5 of theelectromotive furniture drive 2 is used. - The communication connection thus established between the
electromotive furniture drive 2 of the piece offurniture 3 and thedata device 21 also allows, for example, multiple pieces offurniture 3, which are present in a patient room, having identical or different electromotive furniture drives 2 to be unambiguously identified and assigned to therespective data device 21, also if the pieces offurniture 3 are in direct proximity to one another. - The above-described exemplary embodiments do not restrict the invention, which is modifiable in the scope of the appended claims.
- The
power supply apparatus 7 can be provided with an auxiliary power source, which can be, for example, a battery, a storage battery, and/or a capacitor. An emergency lowering function is therefore also possible. It is also possible that thepower supply apparatus 7 is a battery and/or a storage battery. - It is also conceivable that the
transmission apparatus 7 is arranged in theoperating apparatus 10 in the second exemplary embodiment. -
